Abstract: A series of lanthanide complexes with acetylacetonate and a new asymmetrical 5-[p-(4-fluorobenzoyloxy)-m-ethyloxy]phenyl-10,15,20-triphenylporphyrin were prepared and characterized by elemental analyses, molar conductance, UV-Vis, IR, 1H NMR, luminescence spectra and themal analysis. Quantum yields of Q band fluorescence are in the region 0.073-0.097 at room temperature. Complexes have higher stability (decompose until 211°C). The structure that both the porphyrin behaved as a tetradentate ligand and acetylacetonate as a bidentate ligand are coordinated to a rare earth ion also has been proposed.
